1206Y0500154MXTE07

Overview

The Knowles Syfer 1206Y0500154MXTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1206 package with a capacitance of 0.15 µF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, offering a tolerance of ±20%. It incorporates FlexiCap terminals with a nickel barrier and tin plating to enhance mechanical reliability. This device functions as an EMI filter, providing high current handling capabilities.

Feature Summary

• Three-terminal feed-through architecture provides integrated EMI filtering within the capacitor structure.
• FlexiCap terminal design with nickel barrier reduces stress on internal electrodes during board flexing.
• High current handling capability suitable for power line applications.

Applications

• EMI suppression in DC power input lines
• Filtering in board-flex sensitive environments
• Noise reduction in automotive electronic modules

Procurement Notes

Verify the complete part number including suffixes to ensure correct terminal configuration and termination material. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for specific handling requirements related to the FlexiCap technology during assembly processes.

Selection Notes

Select this component when simultaneous decoupling and EMI filtering are required in a single footprint. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Ensure the operating voltage remains below the 50 VDC rating and consider the physical dimensions of the 1206 case size for PCB layout constraints.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs. The series addresses common failure modes associated with mechanical stress in surface-mount devices. The 1206Y prefix indicates the case size and voltage class within the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1206 package. Standard two-terminal capacitors cannot replicate the filtering performance. Verify that alternative parts support the required current ratings and maintain similar impedance characteristics at target frequencies.
